sh-Oligopeptide-4 ●
TL;DR. This ingredient is used as a skin-conditioning signal peptide active, added to formulas to support smoother-looking, more resilient skin. It is not a cleanser or preservative; its role is low-level bioactive messaging in serums, creams, and eye products.
What does sh-Oligopeptide-4 do in a cosmetic formula?
This ingredient is used as a skin-conditioning signal peptide active, added to formulas to support smoother-looking, more resilient skin. It is not a cleanser or preservative; its role is low-level bioactive messaging in serums, creams, and eye products.
Is sh-Oligopeptide-4 clean?
From a clean-beauty perspective, it usually has low odor, low sensitization potential, and no common restricted-list profile. The main scrutiny is documentation: source, recombinant or synthetic manufacturing route, residual proteins, endotoxin control, and preservative quality in water-based formulas.
Is sh-Oligopeptide-4 sustainable?
It is typically made by biotechnology or peptide synthesis rather than harvested from plants or animals. Peptides are expected to break down to amino acids, but purification can be water and energy intensive, so supplier transparency matters.
Is sh-Oligopeptide-4 COSMOS-approved?
It is not an automatic COSMOS-organic or COSMOS-natural fit; acceptance is condition-dependent and would require documentation of compliant non-GMO production, processing aids, and residues. Green Chemistry alignment is mixed: the molecule is biodegradable and used at low levels, while synthesis or fermentation purification can be resource intensive.
How does sh-Oligopeptide-4 work chemically?
The molecule is a defined short amino-acid chain, so its performance depends on sequence, purity, and protection from protease contamination in water-based systems. It is typically used at very low active levels in leave-on products, and formulators usually keep it in mild pH ranges and add it during cool-down to limit degradation.
